"Hazrat Mahdi (pbuh) will not appear until a village in the land of Sham known as Haresta is destroyed." (Mer'iy ibn Yusuf ibn Abu Bakr ibn Ahmad ibn Yusuf al-Maqdi'si "Faraid al-Fawaid al-Fikr Fi al-Imam Al-Mahdi Al-Muntadhar")

“When a bridge is built to Baghdad and comets appear from the east, then the cavalry of an army will be killed on the bridge.”(Muhtasar-u Basair ad-Darajat p. 237 and At Tashrif Bil Menun p. 367 and Bihar Vol. 41 p. 178)

The Harasta region appeared just like that, “There will be disorder in the region of Harasta and a bridge in Baghdad will be torn down,” he says. Look at the detail, “A fire that will illuminate the necks of camels.” It has all come true. But people do not generally make big changes without big signs. That is why in order for the way of the Mahdi to come about Allah will bring about great signs in the days to come. Great things will happen, insha’Allah. People will say, “Something extraordinary is going on.”

They imagine that someone will do something very clever and then will emerge as the Mahdi and rule the world. Not at all. Nobody can appear who is not destined to do so. Whoever rules, is the person who is destined to rule. You may think the person emerged by chance, but he will be the person appointed in destiny, insha’Allah.
